The little Bosch sticker on the outside of my ECU is no longer intact...The question is...Is it the correct ECU for a 1973 2.0l...

Is there any indentifier inside of the unit?

As you may or may not know...The 73 2.0l has a specific ECU/MPS/TempII sensor with resitor, setup. I have always had problems with the D-jetronic...who has not? I may be able to set up using a later ECU, however, the exact bosch part number on the spare is also worn away...So, Can you determine what unit it is from data on the inside of the case?

One step ahead...I thought I would give the rest of us D-Jet novices a shot...Once I find out I will post results...I can't tell you how many times I passed up an ECU at the swap meet because I could not find a part number...@ five bucks a pop I should have bought all of them....Thanks Scott

I responded to Scott via email, but I thought I'd post this for general interest. If the label is missing, ID'ing the ECU can be difficult. Some, but not all, have a sticker on the main board next to the edge connector. Use a small mirror and you may be able to see it. I don't recommend opening the ECU - the metal tabs that hold the lid on are easily fatigued after bending and snap off easily.

Yes...There is a sticker on the mother board near the connector surface...and it is a part number. Unfortunatly, the number is for the 1976 2.0l. The 1973??? ECU did not have the sticker. The mystery of My 73 2.0l continues...I have found a reciept from the PO indicating that a used ECU was purchased and installed. The reciept indicates the the unit is a CU-13x. I think that is a number to designate the unique 73 ECU...

So, Like indicated before..some will have the sticker...others may not...
